'Be it known that I, IVAN D'. THoRnnURG'H, a.I citizen of the United States, residing at at each point.

Gakland, in thegcounty of Alamedafand Y State ot California, have invented certain new and useful Improvements'in Machines A "for ReJTOrming Can-Bodies, of Vwhich 'the following a specification.'

The presentV inventionk relates to an ap-v ing parts 'is such vthat the can bodies are'interinitt'ently moved from point to4 point, and.

successively and independently operated on This construction involves the stopping and startingof a` great number of parts in the mace1ie,ftlierebycausing a considerable Waste o energy andtime. It is the object of the present invention therefore, to providea machine for the described *purpose in which' the can'. bodies j are continuously operated on, and 1n which the various parts are in'lcontinuous-Inovement, and which consequently performs its lfunctions more rapidly and more eiiiciently 'than any device new k'nown to the art.

, VIn order to comprehend the invention ref- .I erence should be hadto the accompanying v sheets of drawings, in whichy Figure 1 is a perspective view of the` can body reforn'iingmachine. Fig. 2 isa vertical longitudinal sectional view takenv on a plane. represented by the'lin'es w-w of transverse taken .in the direction of Fig. l of the drawings, and viewed in the direction of the arrows. Fig. 3 is a vertical transverse sectional view, taken in the direction ofthe arrows' on the line arfof Fig. 2 of the drawings,'showng a series or iattened can bodies within the can bodyV bolder, a body about to be reformed after hav-ing beenk removed vfrom the holder, und

a reformed body about to be discharged from the machine. l Fi 4 is a vertical MACHINE FOR RE-FORMING'v CAN-BODIES.

` In the drawings, the numerab-Mlmrepresents a suitably constructed base" or bedplate for supporting the various parts of the machine and upon which are mounted upwardly extending brackets 2, which carry a horizontal rotatable shaft 3. shaft 4, shown in the drawings as supported in ybrackets 5 resting upon the bed-plate 1, is provided With-means, as, 'for example, a pulley 6, Fig. 1 of thedrawings, for receiving power from `an' outside source, not shown. in the drawings, and drives the shaft 3 by means of the spiral gears 7 and 8,'Figs'. 1 and' 2 of the drawings.

Supported byvandfixed tothe rotating horizontal shaft 3 is a rotary driven spider consisting. of a hub 9 upon which are {two spaced, radially disposedplates '11 and v12.,

A drive Figs. 2 and 6 of the drawings, preferably integral with vsaid hub-9. The plate 12- carries two rearwardly extending, spaced,

axiallydisposed plates 14V and 14', Figs.A 2

' 'and l of the drawings7 thel'outer edges 'of which are joined together by peripheral webs 13 and. 13.. These webs 13 and 13 are provided with guide-ways'l and 15 respectively, in which are slidabl-y mounted blocks 16 and lGsa id blocks carrying for-v wardly extending studs 17 and 17', Figs. 2, -3 and 4 of the drawings. The studs 17 and 17-. are provided as shown in Fig. 2 of the drawings with collars l9fand 19 adjacent to the blocks 16 and 16', tapered or conical heads-18 and 18, and rotatably mounted cylindrical sleeves or mandrels 21 and 21 intermediatel said collars and said heads, said sleeves 21 and 21 being formed with .piniomtoothed sections 22 andf22f at their rear ends. "The forward endplate 11 has suitably formed in the inner face there` of' the spaced sockets 23 and 23" in aline- I nient with said tapered lheads 18` and 1S respcctively, and within which said heads "connection between the two blocks `16 and 16, any forward sliding movcmentof the i tion ofA said shaft block 1G will cause a, corresponding rearward movement of thev block 1G', and vice versa. The blocks16 and 16 are further provided with outwardly extending pins 28 and Q8" respectively,upon which are rotatably mounted cam-following rollers 29 and S29.

A"segmental.semi-circular cam-face 30, Figs. 1 and s1- of the drawings, `formed upon a bracket 31 supported by the base l, is adapted to engage the` cain-following rollers 2l) andlll ofthe sliding blocks 16 and 16 as the same are successively brought to the top of the machine by the rotation of" the shaft 3, and by such engagement tohold one of said blocks 16 or 16 at the forward limit of its travel during apart ot' the revoluf A. short segmental camfface 32, Figs. 1 and E2 of the drawings, carried by a slide 33 operating in horizontal guidenvays 34 supported in a plane parallel tothe shaft il, by the bracket 35, is given a fore and 'aft reciprocatingr movement by alink 3G connecting said slide 33 `to alever 37 fuicrumed in a bracket 38 'on the base 1, said lever 37 being operated by an eccentric 39 on the drive shaft el, the' strap 4() ol which pivotally connected to said lever 3'? at il by a short connecting rod 42. The re- (iiprocating movement ot' the slide 33 is so timed with respect to the rotation of the shaft 3 that said slide 33, 'with its segmental cam-face 32, is at the extreme rearward limit of its travel at the moment that either fone of the cam-rollers 2l and Q9 is brought into a position to engage said cam-tace 3Q; and that upon the beginning ot' such engagement, the slide 33 is moved forward to bring its cam-face 32 into alinemenl'l with the stationary crulrsur'l'ace 30, as shown in Fig. l oi', the drawings.

The

relative positions of the mandrels Q1 and i1 are maintained by the engagement of the l of the cylindrical ironing track 45,Figil "of the machine.

cam-roller 29 of the block 1G with the stationary cam-face 30, until, by the rotation of the shaft 3, the mandrel 21 is brought to the top of the machine, and its cam-roller 29 `engagesthc mov-able cam-face 3Q. By this .time the cz\ni`1'oller :29 has run olf the lower.. end of the stationary cam-face 30, so that when the sliding cani-face 3Q is again moved forward by the action ot theV slide 33, the relative positions oi the mandrels 21 and 2ll are reversed.

A semi-circular bracket 42h-Figs. 1 and 3 of the ('lrawings, supported by the base l, is positioned to partly inclose the space between the revolving transverse plates 11 and 12,-Figs- 1 21 and 3 of the drawings.

A suitably constructed magazine or holder 48,. Figs. 1 and 3 oiY the drawings, adapted to contain a suppl",Y of fiattened can bodies 45.) placed one upon the other and with their longitudinal axes parallel to the axis of the machine, is supported slightly in advance of the upper end or beginning of the ironing track 4:3, upon backets 50 extending upwardly1 from the hase. 1. The sides and front walls` of the holder d8 are cut away, as shown at 51, in Fig. G of the drawings, to permit the passage thereunder of the revolving transverse plaies 11 and 12. A plato T2, Figs. $3, 5 and G of the drawings,,forms the bottom of the holder 48, a slot 53 beingr formed between said bottom plate :'12 and the iront wall 4S of the said holder 48 to provide a discharge opening for the lowcrmost llatloned can body fill within said holder 4S.

Oppositely disposed cylindrical extensions 54, Fig. (i of the drawings. are formed in the upper end portions of the transverse plates 11 and 1Q adjacent to the mandrel Q1, and within these extensions arel slidable pins F5, having llattcned points or lingers {dh-Figs 5.

At the same time the, pinion-teeth-22 ofsaid mandrel 21 engage the-gear rack 46, and said mandrel is forced to roll along the ironing track 45,
